Small enough to disappear in your pocket. Tough enough to be there when you need it.

The Dark Energy Poseidon Nano is proof that preparedness doesn’t have to be bulky. Designed for everyday carry, travel, commuting, and unexpected emergencies, this ultra-compact power bank delivers reliable backup power in a package small enough to fit comfortably in your pocket, sling, purse, glove box, or everyday carry kit.

With a 3,000mAh battery, the Poseidon Nano provides approximately 50–70% of a smartphone charge—often just enough to get you through the rest of the day, make an important call, navigate home, or send that one last message when your battery is running low.

Built to withstand the realities of everyday life, the Poseidon Nano features an IP67 waterproof and dustproof rating, reinforced impact-resistant construction, and reliable operation in temperatures ranging from -20°F to 120°F. It also holds a charge for more than three years in standby mode, making it an excellent addition to emergency kits, vehicle kits, travel bags, and everyday carry setups.

Wireless MagSafe-compatible charging and USB-C output provide flexible charging options for modern devices, while built-in surge protection and voltage regulation help protect your electronics. A leather finger strap makes the Nano easy to carry and deploy, while integrated LED indicators keep you informed of remaining battery life.

When you don’t need a full-size power bank but still want dependable backup power close at hand, the Poseidon Nano delivers.
